1) If an atheist becomes selfish, others have no reason to be discouraged. But see what happens if a religious leader becomes selfish, many may copy his behavior. [Many people know how lavishly Rutherford lived even during Great Depression]
2) If an atheist becomes altruistic, he will inspire more people than religious leaders did, hence is worthy of double reward.—James 3:1
Hence I never try to reason with an atheist for the simple reason that one can be a true worshipper if he has love, rather than a belief in God. (James 1:27) Belief in God may automatically arise later as happened in the case of a former atheist (Dr. Michael Newton). His patients—including atheists and religious people— who came for Past Regression Treatment were, under hypnosis, talking about God and soul unanimously.
